Well, look forward to spammers using this to bypass the spam filters...

Also using similar unicode characters in your username for nefarious spoofing attacks or worse -- https://labs.spotify.com/2013/06/18/creative-usernames/ This is called a Homoglyph attack. If you accept unicode for strings that should be "unique" (eg username), there are various normalization schemes that basically convert equivalent-ish looking characters into a consistent hash. I have no doubt spam filters use this…

That really has to get fixed though.

It doesn't and shouldn't. The whole point of having Mathematical Alphanumeric Symbols as separate unicode code points, rather than just using normal latin characters with style markup, is so they can be used when the different letters have semantically different meanings -- in particular in maths when 𝘹 and 𝘅 can be in the same formula, representing different concepts. They're not a replacement for style markup. In…

This reveals all kinds of bugs in current software. For example, if I use the tool to make a url italic, then pasting that url into Chrome's url bar gives me back a bunch of unicode rectangles. But that's not what I wanted. I wanted Chrome's url bar to interpret those unicode code points as an italic version of the actual unicode code points I want. Chrome should add a check for edge cases like these and add branches…

I can't tell if you're being serious or tongue-in-cheek, but I like this comment nonetheless. Did Unicode ever have any business assigning separate code points for italic versions of latin glyphs? Am I ignorant as to their true purpose? EDIT: SEMI just answered my second question. Math. Makes sense.

HN supports italics it's not entirely plain-text
